These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

frontend-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Frontend Design Skill

Для продуктового интерфейса общая точка входа — ui-design: единый контракт дизайна, реализации и проверки. Прочитай его один раз, если он ещё не загружен; затем вернись к нужным референсам ниже, без повторного обхода ссылок. Редактируемые hero/баннеры, инфографика и отдельные визуальные ассеты также описаны там. Этот файл — веб-специализация, не второй независимый процесс и не замена правил продукта.

Этот скилл — о создании визуально выдающихся интерфейсов. Не просто рабочих — а таких, где дизайн говорит сам за себя. Основной принцип: каждый интерфейс должен выглядеть как работа senior-дизайнера, а не как «шаблон из интернета».

Золотые правила хорошего UI

1. Иерархия важнее красоты

Пользователь должен за 3 секунды понять: что это, что важно, что делать.

  • Один главный акцент на экране
  • Размер и вес текста = важность информации
  • Пустое пространство — не «пустое», а воздух для восприятия

2. Консистентность убивает хаос

  • Один радиус скругления на весь интерфейс (4/8/12/16px)
  • Одна шкала отступов (4px / 8px / 12px / 16px / 24px / 32px / 48px / 64px)
  • Максимум 2 шрифта: заголовочный + основной
  • Максимум 3 цвета: основной, акцентный, нейтральный

3. Детали создают профессионализм

/* Плохо — резкие переходы */
button { background: blue; }
button:hover { background: darkblue; }

/* Хорошо — всё плавно */
button {
  background: #3b82f6;
  transition: all 0.2s cubic-bezier(0.4, 0, 0.2, 1);
  box-shadow: 0 1px 3px rgba(0,0,0,0.1);
}
button:hover {
  background: #2563eb;
  box-shadow: 0 4px 12px rgba(59,130,246,0.4);
  transform: translateY(-1px);
}

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
